Support

I will not be able to offer support or reliable maintenance for this software,
or any of its plugins. Functionality may be changed without notice. This software
is (for now) indefinitely in pre-release mode, and there are no current plans
for a stable release.

Your best bet for using this software is to fork it and maintain your own
codebase. I will gladly take pull requests under consideration if you feel like
contributing.
